Patent number: 9567667Abstract: System and method of insulating film deposition. A sputter deposition chamber comprises a pair of targets made of the same insulating material. Each target is applied with a high frequency power signal concurrently. A phase adjusting unit is used to adjust the phase difference between the high frequency power signals supplied to the pair of targets to a predetermined value, thereby improving the in-plane thickness distribution of a resultant film. The predetermined value is target material specific.Type: GrantFiled: September 18, 2014Date of Patent: February 14, 2017Assignee: Tokyo Electron LimitedInventors: Shinji Furukawa, Naoki Watanabe, Hiroshi Miki, Tooru Kitada, Yasuhiko Kojima

Publication number: 20150343369Abstract: In a chemical plant 100 including a carbon dioxide recovery unit 10 and a urea plant 11, the carbon dioxide recovery unit 10 treats combustion exhaust gas from a boiler B to separate and recover carbon dioxide. Low-pressure steam 33 generated in the urea plant 11 is supplied to the carbon dioxide recovery unit 10 as a heat source for its regeneration tower reboiler. Carbon dioxide 22 recovered in the carbon dioxide recovery unit 10 is sent to an EOR facility, a storage facility, and the like outside the plant. Thus, the low-pressure steam generated in the urea plant 11 is effectively used as a heat source for the carbon dioxide recovery unit 10.Type: ApplicationFiled: January 28, 2014Publication date: December 3, 2015Applicant: TOYO ENGINEERING CORPORATIONInventor: Yasuhiko Kojima
